CNI24 SERIES VHF/UHF/L-BAND ANTENNA The CNI24 Series multiband very high frequency/ultra-high frequency (VHF/UHF)/L- band antenna was designed for use with the ARC 182 radio and L-band equipment. The 12-inch tall fixed-tuned blade configuration provides enhanced VHF, frequency modulation (FM) and amplitude modulation (AM) band performance when compared to other 8- and 9-inch blades. Optional external diplexers are available, including the FM34 Series that can provide up to 85 decibels of isolation between the VHF/UHF and L-band frequency ranges while minimizing additional insertion losses. The CNI24 Series has been designed for deployment on high-performance (Mach 2.0+) aircraft. The -12, -15, and -17 broadband models have been designed to support interferometer-based direction-finding applications and are phase-matched on a 100 percent basis.
